Hebrews 12:23

for they could not stand that which was commanded, “If even an animal touches the mountain, it shall be stoned”.

So fearful was the appearance that Moses said, “I am terrified and trembling.”

But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable multitudes of angels,

to Jesus, the mediator of a new covenant, and to the blood of sprinkling that speaks better than that of Abel.

See that you don’t refuse him who speaks. For if they didn’t escape when they refused him who warned on the earth, how much more will we not escape who turn away from him who warns from heaven,

whose voice shook the earth then, but now he has promised, saying, “Yet once more I will shake not only the earth, but also the heavens.”
